When existing elements are recycled (ie crushed and used as aggregate) on site, they can contribute to awarding credits as recycled aggregates.
This issue aims to recognise and encourage the use of recycled and secondary aggregates and addresses waste rather than materials. It refers to recycled aggregate obtained on-site or off-site, based on materials identified as waste and removed during construction works.
Previous incorrect KBCN text amended. CN 'Aggregates in existing applications' to be amended accordingly in next reissue of the RFO Technical manuals.
